notes
This species mostly occurs as an inquiline with Dasineura trifolii, but also seems capable to induce galls autonomously. In the case of Dasineura the whole leaflet is galled and swollen, while in Tricholaba only the central part of the leaflet is weakly galled. The larva is pale orange-red; pupation in the soil.
